| The main objective of this study was to identify algal diets that maximize the survival and growth and alter the biochemical content of Pecten maximus larvae with the aim of improving metamorphosis. We also evaluated the potential of the cryptophyceae Rhodomonas salina as a food source for these larvae. Two flagellates, Isochrysis aff. galbana (T) and Pavlova lutheri (P), and two diatoms, Chaetoceros gracilis (C) or Skeletonema costatum (S), were tested as two ternary diets, namely PTC and PTS. PTC and PTS were compared with diets that also included R. salina (R). The addition of R. salina and the replacement of C. gracilis by S. costatum in the traditional hatchery diet seem to be two interesting alternatives for increasing the productivity of larval... |

| L'aquaculture et la pêche ne font pas toujours bon ménage : conflit pour les zones de production (élevages en mer), concurrence sur le marché (poisson d'élevage / poisson "sauvage"), et surtout conflit sur la gestion des stocks naturels de juvéniles, parfois exploités pour l'approvisionnement des élevages au détriment d'une production naturelle d'adultes pour le stock exploité par pêche (palourde du golfe du Morbihan, crevettes tropicales, etc). En d'autres cas les techniques d'élevage peuvent se révéler au contraire un outil précieux pour la gestion des stocks naturels, particulièrement pour des animaux plus ou moins sédentaires comme les Mollusques ou les Crustacés. Ici l'élevage des juvéniles va permettre de conforter le stock naturel des animaux... |

| Aquaculture production of scallop has been identified by a series of technical operations during the past ten years programme under a partnership involving the fishermen organizations with regional and national grants. 3 million juveniles have been produced annually, giving a potential recapture by fishing of 100 to 120 tonnes 3 years later. Results in terms of technical and economical approach have pointed out the principal unknown factors responsable for high costs. 7he pilot programme aims to increase the production to reach a level of 5 million juveniles to support the fishery of the rade de Brest and induce new management of the resources. Two priorities were selected, control of the reproduction in the hatchery to obtain reliable larval and... |
